Zeolite 4A Molecular Sieve
Product Description
Ball-tec 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms, thereby excluding those larger. It can be regenerated by either heating in the case of thermal swing processes or by lowering the pressure in the case of pressure swing processes.
Typical Chemical Formula:
Na2O. Al2O3. 2SiO2. 4.5H2O (SiO2: Al2O3 ≈2)
Typical Application:
• Deep Dehydration of air, natural gas, alkanes, refrigerants and other gases.
• Preparation and purification of argon.
• Static Dehydration of pharmaceutical packaging, electronic components and perishable substances.
• Used as dehydrating agent in paint, fuel and coating.
